I’m using bio tabs so if it’s nutrient burn I can’t do anything to stop it

Organomananswered grow question 4y ago

To me it looks like nutrient burn not light burn, which would cause the leaves to go brown and crispy. 18/6 is much more plant friendly and a 100 watt light would have to be almost touching the plant to cause burning. I would be either reducing the feedings or the nutrient strength and would be quite happy to have the light at 100%, it is only 100 watts after all. Also I would be ensuring there is run off each irrigation, this will help slow the build up of nutrient salts in the substrate. Hope this helps,.......... Organoman.

Deficiency/Light Stress Issues What else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

Possible deficiency/humidity/pH problem I've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater

Discolored, burnt and curled up tips on higher leaves Several symptoms, always on tips of higher leaves : they are discolored/burnt or burnt/curled up. LED @40cm (deemed 70% of 300W) and I just gave them the 2nd flowering feeding, 4 days after first one (pots were very light). I was planing to start compost tea... What should I do ?

Seedlings struggling This is day 10 since they popped out and it just seems as if my seedlings are stunted. I kept an 85w CFL about 10cm from their tops for the first week and then raised it up to about 15cm for the next few days. They had humidity domes. Temp was 20°C-24 in day

What are my leaves telling me?Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Yellowing, burnt tips and edges Hello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please help

Bright tips on new growth Any ideas on the bright/yellowish tips? Nute-burn is unlikely since I did just feed pure water to that point. Maybe light burn? Moved the lights around 5 cm higher. My tap water is around 7.2 pH

Lower leaves yellowing and wilting quickly Soooo Just went to water this beautiful lady and as you can see from the pictures 2 days ago and she was healthy. So this evening i found that the lower large fan leaves and the smaller fan leaves on bud sites are drooping and yellowing. This looks like its nitrogen or lockout?

My leaves got burnt a little bit, The leaf tips have a bit crumbly texture, and the new top leaves are a bit yellow. I was wondering if this was caused by my nutrients or the heavy sunlight they get or anything else? Thanks a lot ;) greets.

Heavy fast yellowing I flushed my plant because of too high ppm reading from run off and now she seems to be going all yellow. Is this normal for this stage of the grow (all trichomes still white and small buds) or is this a definite nutrients deficiency during flowering?

Grow Lights Is it okay to use an LED Light 1000 watt (4x4x80" tent) & a UV Light 1000 Watt in a 4x4x80" grow tent for 3 plants. I want more light, I have plants growing slowly so I'm hoping to adjust the amount of light I have would speed up their growth. LED is white spectrum & UV blue-veg
